A comprehensive review Of Onnit’s Krill Oil

One of the most admired human traits is cognitive ability. Yes, a lot of people will look at outside beauty but if you really look at the people who make a difference in the world and who constantly wow others, what they have going for them above everything and everyone else are their brains. For the longest time, scientists have been looking for ways not only to improve human cognitive functions but also to ensure that thinking capacity, reasoning and all those other traits that come from really good cognitive abilities do not fade as we age.

Scientists have for a long time argued that the answer to better cognitive function is omega-3 fatty acids. While it is true that omega-3 fatty acids will improve thinking as well as afford us a number of other benefits, the scientists at Onnit have discovered something even better: Krill oil.

Krill Oil

Krill oil is a form of oil that is harvested from deep sea crustaceans. Its has a number of benefits over fish oil which has also been held in high esteem for quite a long time as far as improved cognitive performance and abilities are concerned. In this review, we are going to have an in-depth look at Krill Oil from Onnit and we are going to see why it is much more beneficial than fish oil.

A look at the pros and cons of Krill oil

The pros

  • Krill oil has been associated with better cognitive function in its users.
  • It is made from natural ingredients meaning that it is not going to harm you in any way.
  • A number of athletes who use Krill oil have endorsed it as being of benefit to them,their health and performance
  • The constituents of Krill oil which we will look at in detail below are thought to contribute to weight loss as well as improved health.
  • By helping reduce the amounts of harmful cholesterol in the blood, Krill oil does help promote a healthier cardiovascular system

The cons

  • Although people who have used Krill oil for a very long time do not report any adverse effects, Onnit does not provide any clinical trials on this supplement.
  • Some people see Krill oil as a little bit expensive which could hurt the brand but does nothing to disapprove the fact that Krill oil works and much better than fish oil in that regard.

So, what is Krill oil?

On their website, Onnit says that Krill oil is like fish oil, only better. If user reviews are anything to go by, it certainly is! What then, is Krill oil? Krill oil is oil that is harvested from crustaceans that are found in pristine antarctic waters. The krill so harvested is rigorously tested to ensure that it is free of any toxic heavy metals which have for the last few years become a major problem in seafood based supplements and foods. To see how Onnit collects their Krill, be sure to click on the video below.

Krill oil has several benefits over and above fish. This is the quality that makes krill oil a better supplement. There is also the fact that scientists have looked at both krill oil and normal fish oil and found out that krill contains a wider variety of beneficial fatty acids as well as higher quantities of these fatty acids than fish oil. It is worth noting that Krill oil as Onnit’s product has other vitamins and supplements added in so as to add on the number of benefits you get from incorporating this supplement into your daily life.

A detailed look into Krill oil and understanding what makes it Unique

We cannot talk about why Krill oil is considered to be superior to fish oil without looking at makes up krill oil.
I mentioned earlier that Omega-3 fatty acid are essential dietary components for everyone. They have been proven to be essential in the development and maintenance of various vital bodily organs as well as their well being. Fish oil contains eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These are long chain polyunsaturated fatty acids, also known as PUFAS, that cannot be synthesized by the human body. The only source of these polyunsaturated fatty acids is dietary and in particular fish and krill oil. These fatty acids have been shown to play critical roles in the development and improvement of cognitive function as well as helping fight obesity through various mechanisms.

Although both Krill and fish oil both contain EPA and DHA, there are higher quantities of phosphatidylcholine (PC) in Krill oil than there is in fish oil. The higher levels of this phosphate group in the fatty acid chains of krill allow it to be much more easily digested and absorbed in the small intestines. This phosphate acid group is also responsible for the rapid incorporation of the essential fatty acids so broken down and absorbed into the lung, liver tissues and the brain.

In one study, scientists found out that humans who had been given a supplement which had krill oil containing about 65% of the total levels of omega-3 in fish oil had the same EPA and DHA plasma levels as those who had been given fish oil containing 100% of omega-3. This was despite the fact that those given the krill oil had been given a smaller done by about 35%. This was explained as being due to the fact that the phospholipids found in krill oil had a much better rate of absorption which allowed for a much faster rate of incorporation into important organs and tissues.

What differentiates Krill oil from fish oil?

There are several reasons why Krill oil is considered to be superior to fish oil the first of which is the ingredients that are contained therein.


These ingredients are:
1.Astaxanthin – This is a very powerful antioxidant that is best known for giving salmon meat its red color. It is classified as a carotenoid. Carotenoids are known to be very powerful antioxidants that work thorough sequestering singlet oxygen. Singlet oxygen is very reactive as it is responsible for aging through the breakdown of DNA, lipid membranes as well as the proteins that make up the bulk of our cells. By sequestering singlet oxygen, astaxanthin helps protect the fatty acids that are found in the Krill oil that you take as a supplement from being broken down. It has also been shown to have very potent anti-inflammatory action in the cardiovascular system.
I think it is worth mentioning that in studies done independently, a group scientists found that astaxanthin not in combination with the omega-3 fatty acids that are found in Krill oil can go a long way in improving immune functions while at the same time lowering DNA damage and decreasing inflammation. Astaxanthin has also been shown to help help strip plague off arterial walls through increasing the plasma quantities of HDL cholesterol.
2. EPA and DHA – Collectively, these fatty acids are known as omega-3 fatty acids and they are what gives Krill oil its potent activity. They have been shown to promote healthy skin as well as reduce the chances of getting a heart attack. When used in conjunction with regular exercise and a good diet, these omega-3 fatty acids have been shown to help lower certain blood triglycerides as well as increase the plasma levels of essential cholesterol in form of HDL. Remember how that helps the cardiac system? DHA and EPA are also well known agents of fighting cellular inflammation. This one property is what makes Krill oil beneficial in the joint care and rehabilitation that is often essential for arthritis patients.

There are lots of benefits of using Krill oil

We have covered most of the benefits that are to be had from using this supplement on a regular basis. To recap, some of the more apparent benefits are helping with weight loss, reducing the chances of heart attacks by reducing the amounts of dangerous fatty acids and plague in your cardiovascular system as well as helping ease inflammation and in this way the symptoms of arthritis.

I would like to bring your attention to the cognitive benefits you get with Krill oil. Recent studies have proven that Krill oil contains the same benefits as fish oil as far as improving cognitive function is concerned. The advantage that Krill oil has over fish oil is the addition of the phosphate groups that form phosphatidylcholine. The omega-3 fatty acids, when incorporated in phosphatidylcholine, act more efficiently on brain function than those incorporated into triglycerides as are the omega-3 fatty acids found in fish oil. The fact that the Krill omega-3 fatty acids bind to phosphatidylcholine, a combination of phosphate groups and acetycholine, implies that they have already crossed the brain barrier. This helps to reinforce the idea that Krill oil has a much better bioavailability than fish oil and is thus more potent at lesser doses.


One final benefit that most people do not know about is that due to the combination of the phosphate groups in Krill oil and the acetylcholine in the brain wall to form phosphatidylcholine, Krill oil can help lower the levels of cortisol in the body. This is very helpful for people with stress.

Who can use Krill oil?

To be perfectly honest, everyone who is looking for improved memory, brain function as well as reasoning ought to get Krill oil and incorporate it into their daily dietary supplements. However, there are those it is highly advised for and these include the following:

  • People who are looking to lose weight. Remember we said that the omega-3 fatty acids help reduce the amounts of low-density lipoproteins. These LDLs are known to be harmful and promote weight gain.
  • Krill oil is also advised for those who are looking for help with cardiovascular problems brought about by weight gain.
  • Patients who suffer from arthritis can also benefit hugely from the anti-inflammatory properties of the astaxanthin found in Krill oil.

Side effects and warnings

I cannot stress enough that this health supplement is made from 100% natural product. This means that it is perfectly safe for everyone who uses it. Granted, all of our bodies react differently to different products and supplements. You are therefore advised to see a healthcare specialist if you experience any symptoms or adverse side effects when using Krill oil.

I have to say, if you are not taking this supplement, you are missing out on a lot. From helping with improved cognitive functions, reduction in stress, reduction in amounts of harmful phospholipids in the body as well as helping with weight loss and the increase of helpful HDLs in the body, this is an all round supplement. I recommend Krill oil for everyone and I am going to start using it and post my detailed review on it online soon.
